I read what the article says about Angry Birds. Basically it says, "You can't talk about the concept of casual gaming without mentioning Angry Birds in the same breath. It's the ultimate modern-day casual game series." and "game has been downloaded a bajillion times (12+ million to be more precise) and is available on just about any device that has a touchscreen and can connect to the internet." So yea, I'm guessing its on the list since its such a casual game.

What this guy said. It's become pretty much a cultural icon, and it's doing a lot to push the emerging mobile gaming market, in much the same way that Tetris proved to be a tremendous boom to the handheld gaming market in the 80s and 90s.

Ah, I remember playing Oregon Trail on those old Apple II's back in elementary school. Getting a good hunting map, hitting everything that moves, and then being told you can only carry away 200 pounds of what you shot. Fording a shallow river, only to sink and have a party member drown. Getting killed by random snakebites or sudden outbreaks of dysentery or malaria. Good times.

Not kidding. Look at what Tetris did in the late 80's early 90's for mobile gaming. Tetris was not a hardcore videogame, it was a really good puzzle game, but it was as casual a game as you can get back then. It was extremely popular among gamers and non-gamers alike. They both sold tons of copies and made large marks in changing the video gaming indsutry. We have to give props where props are needed and Angry birds deserves its props.
